Operation

The unit can be easily operated 
with the room temperature 
controller available as an accessory 
or a controller to be provided by 
the customer. It is also possible to 
activate the system using a building 
management system.

Use the separate operating manuals 
for this purpose.

The controller is connected to one 
or more units by a cable. If a group 
controller is used the maximum 
current load must be observed.

System layout

The unit is designed for 
a 2-conductor system. 
The 2-conductor system has 2 
medium pipes (conductors: supply 
and return flow) for cooling using 
a cold medium and 2 medium 
pipes for heating using a warm 
medium. In cooling mode the 
combined cooling / heating heat 
exchanger in the indoor unit 
extracts the heat from the room air 
by absorbing it into the operating 
medium. A circulation pump 
transports the heated medium to 
a chiller/warm water generator 
which extracts heat from the 
medium or heats the medium in 
a heat exchanger. The cooled/
heated operating medium is then 
fed once again to the unit in the 
medium circuit.

Room temperature controller

Installation in the unit

Help by reducing energy usage 
in stand-by mode! If the unit, 
the system or the components 
are not being used, we 
recommend disconnecting the 
power supply.  
Our recommendation does 
not apply to safety relevant 
components.
